A method of forming a surface covering includes supplying a surface covering raw material. The surface covering raw material includes a substrate and a foamable layer formed on the substrate. A foaming inhibiting composition is applied in a predetermined pattern to the foamable layer formed on the substrate. The foaming inhibiting composition is a non-aqueous composition.

The disclosed latex system comprises a one-component, closed-cell, semi-foam, mastic sealant using gas-filled, flexible, organic microspheres to create a product that is elastic and compressible under pressure without protruding in an outward direction when compressed, thereby allowing the applied sealant to compress in an enclosed, maximum-filled channel unlike typical mastic sealants (while retaining the ability to rebound). This allows the sealant to function as a gasket, and, once fully cured, to have properties including vibration damping, insulating, and condensation resistance. The sealant can be formulated as an air barrier or a vapor barrier and at various degrees of moisture resistance. It may be applied by different packaging variations including aerosol can (bag in can or bag on valve), airless sprayer, cartridge tubes, foil tubes, squeeze tubes, and buckets to be applied using a brush, trowel, spatula, etc. The disclosed mastic sealant can also be formulated to be smoke-resistant and flame-resistant.

A method for manufacturing a foam-molded article by performing a GCP, the method including a step of retreating a mobile side of a mold clamping mechanism of a sealed mold at the same time as when a step of discharging a gas is started, during the step of discharging the gas, immediately after the step of discharging the gas or when a specified delay time after the step of discharging the gas is finished for performing at least one of a mold-back and a core-back to increase a foaming ratio of a foamable resin in a state that a cooling and a solidification of an inside of the foamable resin are not finished.
